Mention was made of RAAF Base Curtin in an earlier post. I'd like to offer some clarification of Curtin's status. It is not an active duty base and no squadrons are meant to be based there during peacetime.
It is one of three 'bare bases' that the RAAF maintain as forward deployment bases. The three bases and their locations are now available on on the net so there's no security breach in posting them here.
They are: -
RAAF Scherger near Weipa, Queensland
RAAF Curtin near Derby, Western Australia
RAAF Learmonth near Exmouth, Western Australia
